【Supercomputer】 Special Maintenance on the login nodes in the System B and C and the Storage System

publication date : Oct.20, 2017

The storage system has become unresponsive for about 1 hour on October 12th and 18th.
It is found that it can be improved by applying a patch to the storage system. Since it occurred twice in a short time, we will apply it by temporary maintenance.

During the maintenance, file access becomes in a wait state. The file access is restarted after the maintenance is completed, so the running jobs are continuously executed as it is in principle. However, there is a possibility that it is abnormally terminated due to the timing of the file access, in that case please re-execute.

Range to be affected: Storage system (file access to /home, /LARGE0, /LARGE1)
Date:Mon. October 23, 2017 9:00 a.m. - 11:00 a.m.

Also, important updates to the operating systems of the login nodes B and C were released, so we will do the maintenance at the same time.
Please note that we will cancel the login session at the start of the maintenance.
We will not perform the maintenance for the login node of the system A, new login will be terminated during the maintenance.

We apologize for any inconvenience this may cause.

The system maintenance has been completed, and all services are now restored as normal. We apologize for any inconvenience that this may have caused you.
